Book Description
Biological psychiatry has dominated psychiatric thinking for the past 40 years, but the knowledge base of the discipline has increased substantially more recently, particularly with advances in genetics and neuroimaging. The third edition of Biological Psychiatry has been thoroughly updated taking into account these developments. As in the earlier editions of the book, there are comprehensive reviews and explanations of the latest advances in neurochemistry, neuroanatomy, genetics and brain imaging— descriptions not only of methodologies but also of the application of these in clinical settings. It is within this context that there is a considerable emphasis in the book on brain–behaviour relationships both within and without the clinical setting. This edition has been enhanced by the inclusion of new chapters, one on anxiety and another on motivation and the addictions. The chapter that relates to treatments has been extended to include the latest information on brain stimulation techniques. The overall book is well illustrated in order to help with an understanding of the text. For the third edition, Professor Michael Trimble has been joined by Professor Mark George as co-author. These are two of the world's leading biological psychiatrists who both have considerable clinical as well as research experience which they have brought to the book. Unlike multiauthored texts, it has a continuity running through it which aids understanding and prevents repetition. This book is strongly recommended for all practising psychiatrists and trainees wishing for an up-to-date, authoritative, easy to digest and acessible review of the latest advances and conceptualizations in the field. It will also appeal to neurologists interested in neuropsychiatry and biological psychiatry or the psychiatric aspects of neurological disorders, as well as other practising clinicians (psychologists, social workers, nurses) in the mental health field.

Book Description
It is now widely recognised that biological psychiatry is rapidly coming into its own. For over the last three decades dramatic advances in this young discipline have been made, all of which attest to the staying power of the experimental method. Those who made this revolution in knowledge happen are a breed of investigators availing themselves of the tools of molecular biology, pharmacology, genetics, and perhaps, above all, the technology of neuroimaging. The introduction of the interdisciplinary method of approach to the study of psychopathology had made it very clear that neuroimaging, as a set of techniques, is unique in that it is gradually providing us with evidence supporting Kraepelin's original view that mental illness is closely associated with abnormal changes in the brain. Broadly speaking, there are presently two structural techniques in neuroimaging - computed tomography and magnetic resonance imaging (MRI) - and three functional techniques - single photon emission tomography (SPECT), positron emission tomography and magnetic resonance imaging (fMRI). Through PET technology, for example, we have learned that, in early brain development, the primitive areas, mostly the brain stem and thalamus, are the first to show high activity in an infant. This is followed by the development of cortical areas by year one. Between the ages of four to 10, the cortex is almost twice as active in the child as in the adult. This information alerts us to what might happen in the way of trauma in abused children, especially those under the age of three. Child abuse increases the risk of physical changes, not only in the stress systems, but also in brain development (Glaser and Weissman). In addition to the difficult problem of post-traumatic stress disorder (PTSD), we have to take into account the possibility of other types of mental illness as the consequences of child abuse. These include depression, eating disorders, and drug and alcohol problems. The combination of PET and fMRI represents a more remarkable example of the power of neuroimaging since the two have made it feasible to map accurately in vitro identifiable cortical fields, or networks. In a landmark NIH investigation of human cortical reorganization (plasticity), persuasive evidence was brought forward showing that the process of learning as a motor task involves a specific network of neurons. These neurons occur in the cortical field that is responsible for that particular task. Such findings are important partly because they provide evidence supporting the current notion that labor in the cortex is divided among ensembles of specialized neurons that cooperate in the performance of complex tasks. Cooperation, then, in this, sense implies crosstalk among ensembles and that signals are both processed and retransmitted to neighbouring ensembles. To understand the workings of these ensembles, much better spatial and temporal resolution in functional brain mapping is required. This can be achieved with an NMR instrument whose magnet is 4.1 Tesla or more.

Book Description
The understanding of how to reduce risk factors for mental disorders has expanded remarkably as a result of recent scientific advances. This study, mandated by Congress, reviews those advances in the context of current research and provides a targeted definition of prevention and a conceptual framework that emphasizes risk reduction. Highlighting opportunities for and barriers to interventions, the book draws on successful models for the prevention of cardiovascular disease, injuries, and smoking. In addition, it reviews the risk factors associated with Alzheimer's disease, schizophrenia, alcohol abuse and dependence, depressive disorders, and conduct disorders and evaluates current illustrative prevention programs. The models and examination provide a framework for the design, application, and evaluation of interventions intended to prevent mental disorders and the transfer of knowledge about prevention from research to clinical practice. The book presents a focused research agenda, with recommendations on how to develop effective intervention programs, create a cadre of prevention researchers, and improve coordination among federal agencies.

Book Description
"Neuropsychiatric disorders and suicidal behaviour represent major contributions to mortality in Canada. Among the many factors associated with psychiatric disorders and suicide, alterations in lipids and cholesterol have been demonstrated both peripherally and centrally, supporting their roles as mediating variables in the underlying neuropathology. Cholesterol (CHL) regulation is a complex and dynamic system, and while animal studies also support a mediating role of CHL on brain function, efforts to determine a biological association in humans have achieved only modest gains. While mechanisms governing cholesterol regulation are not entirely understood, cholesterol is well accepted to have important impacts on a variety of brain functions from neurotransmission to synaptic plasticity and neurodegeneration, with unique contributions from neurons, astrocytes, and oligodendrocytes. Given the extensive regulatory feedback mechanisms and the implications in neurological function, determining a biological basis for the association of cholesterol with neuropsychiatric disorders remains an important area of research. This research aimed to explore the neurobiological mechanism whereby alterations in CHL may relate to neuropsychiatric phenotypes. The results presented in chapter 3 suggest, while no clear differences were found in suicide completers with major depressive disorder, expression of several CHL related genes associate more strongly with white matter CHL levels compared to grey matter, suggesting a potential contribution of SORT1, LPL, and ABCA2, in the regulation of white matter CHL. The results of chapter 4 suggest altered phospholipid levels and expression of lysosomal acid lipase A gene in violent suicides in the prefrontal cortex, which would have important consequences for inhibitory neurotransmission. The results of chapter 4 suggest an increase in 24-hydroxycholesterol in the prefrontal cortex of suicide completers and this could have implications for synapse maintenance and loss in the neuropathology of suicide. In regards to CHL levels, however, little evidence in support of alterations in CNS CHL in neuropsychiatric disorders and suicidal behaviour was noted." --

Book Description
Recent studies regarding the neuropathology of specific neurological disorders suggest that both neurodevelopmental and neurodegenerative processes may play a role. However, in contrast to the neurodegeneration seen in neurological disorders such as Parkinson's and Alzheimer's disease, the term "neuroprogression" has been used to describe the neurodevelopmental aspect of pathological brain re-wiring that takes place in the context of severe psychiatric disorders, such as schizophrenia or bipolar disorder. Within psychiatry, patients with severe psychopathology, such as those depressed patients who eventually commit suicide, have been shown to present with increased inflammatory markers in the brain. A similar increase in inflammatory markers is also found in patients with bipolar disorders and schizophrenia. Thus, oxidative stress, inflammation, and changes in growth factors are thought to be the pathways of neuroprogression. Neuroprogression in Psychiatry provides a comprehensive summary of the current developments in the emerging field of neuroprogression. With contributions by leading researchers in the field, this book examines the role of neuroprogression across a wide range of specific psychiatric disorders, with chapters included on major depressive disorder, anxiety disorder, post-traumatic stress disorder, substance abuse, schizophrenia, and bipolar disorder.
